MRI-based classification of shoulder calcific deposits to guide treatment
Official title: A Novel Classification in Calcific Tendinitis of the Shoulder: Evaluating MRI Localization and Related Treatment Strategies
Run by Koç University · NCT07409818 · Data updated 2026-11-12
This study will try a new MRI-based way to classify calcific shoulder deposits to see if deposit location relates to treatment choices for patients who had surgery for calcific tendinitis.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients with calcific tendinitis who have preoperative shoulder MRI showing one or more rotator cuff calcific deposits and who underwent surgical treatment.
✕Probably not a fit
Patients without available MRI, those managed only with non-surgical care, or those with prior or revision ipsilateral shoulder surgery are unlikely to benefit from this classification.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Researchers will create a simple, treatment-oriented classification of calcific tendinitis based on the location of deposits seen on shoulder MRI. They will apply this MRI-based classification to a cohort of patients treated at Koç University Hospital using existing MRI scans and clinical records. The study will compare how different localization categories relate to treatments received, including conservative care, debridement, side-to-side repair, and anchor fixation. Patients with prior ipsilateral shoulder surgery for other reasons, revision calcific tendinitis surgery, or missing/incomplete MRI documentation will be excluded.
Why it matters
Potential benefit: If successful, the classification could help doctors choose surgery versus conservative care more precisely, potentially improving outcomes and avoiding unnecessary procedures.
How similar studies have gone: Existing classifications based on X-ray and ultrasound exist, but an MRI-based system directly tied to treatment decisions has not been validated.
